Subject: [PATCH] avformat/avio{,buf}: deprecate AVIOContext::written

Originally added as a private entry in commit
3f75e5116b900f1428aa13041fc7d6301bf1988a, but its grouping with
the comment noting its private state was missed during merging of
the field from Libav (most likely due to an already existing field
in between).
